If you or anyone in your party does not hold a passport/national identity card issued by a European Union or European Economic Area member state, then those passengers must print their boarding pass on A4 paper, one sided [i.e. each person must hold their own individual boarding pass, do not print a second boarding pass on the reverse side of the page], and present this to the document check desk at the airport of departure prior to going through security. Passengers without an EU/EEA passport who present a boarding pass at the boarding gate without the document check stamp will be refused travel. At that stage, it may be too late to go back landside to obtain the stamp; so make sure those passengers who need it get their boarding passes stamped landside before going through security.

This holds true for every Ryanair flight that these passengers take. It is not acceptable to show an "old" boarding pass from a previous Ryanair flight with the document check stamp.

All passengers must check in online (except if you opted for the very expensive Business Plus fare) but people who do not hold an EU/EEA passport cannot use the mobile app to checkin and instead must print out their boarding pass as advised above.

You can check in online well in advance. Note that checking in at the airport (fee: £50/€50 per passenger), or having a replacement boarding pass issued at the airport (fee: £15/€15 per boarding pass), is subject to additional fees. They are not as high as they once were - but they are quite high.

Ensure that you are familiar with Ryanair's baggage policies, and that everyone has bought a sufficient luggage allowance in advance. Buying luggage or paying excess baggage fees at the airport on the day of departure is always far more expensive than buying the requisite allowances in advance.

Also note that if your group wants to sit together, you would be highly recommended to buy advance seat selections.
